The prompt ( /\ ) preceding "ADDR" in the display
means that you can change the begin RAM address to
any address within the range of RAM word limit by
entering the hex value with the keyboard. If an entry is
not made, the value defaults to zero (0). If a hex value
appears in place of "ADDR," it is from a previously
entered begin address.
a. If the hex value that appears in place of "ADDR" is
correct, go to step 3.
b. If it is incorrect, enter the correct hex value.
c. If you do not wish to change the begin device
address or block size (step 3), go to step 4.

The prompt ( /\) preceding "SIZE" means that you can
change the block size by entering the hex value with the

b. If it is incorrect, enter the correct hex value, then go
to step 4.
INSERT VIA BLOCK MOVE
Moving Block "B" forward in
memory causes block "C" to be

the same, but is only a fragment
of block "B" and may be edited
or new data may be inserted.
